It is a special type of resistor that acts as electrical resistance and is formed by casting a certain metallic alloy.

The main purpose of these resistors is to limit the electric current to a certain rate. However, beyond this simple definition of the cast resistor, it has some distinguishing features from other types of resistors, thanks to the materials and methods used in its production.

Cast resistors are typically produced by casting high-conductivity metals in alloys with different metals to achieve a specific resistance value.

The composition of the alloy directly affects the overall properties and performance of the resistor. During the casting process, metallic alloys are melted at high temperatures and cooled by pouring them into special molds. Resistors produced with this method have a homogeneous structure and show extraordinary performance even in high energy applications.

This special production method of cast resistor offers unique advantages in terms of both physical durability and electrical properties.

In electrical circuits, such resistors are generally preferred in high power applications, where they must be resistant to temperature fluctuations, and where they may be exposed to mechanical stress.

Working Principle of Cast Resistors

Cast resistors are elements that work based on the principle of conversion of electrical energy into thermal energy. So, how do these resistors work and what are their roles in electrical circuits?

Cast resistors are often used in high power applications. Thanks to their ability to absorb high-energy electrical currents, these resistors absorb and convert large amounts of energy into heat without overheating or being damaged. The specific resistance of the cast material forms the basis of the operating principle of these resistors. When electric current passes through the resistance, energy is lost due to the specific resistance of the material. This energy loss causes the resistor to heat up.

Especially in industrial applications, such resistors are used in high-energy circuits to prevent overheating, limit the current in the circuits and keep electrical loads balanced. Cast resistors have a metal body produced by the casting method. This metal body ensures that the resistor can absorb and dissipate high amounts of heat. Thus, it ensures safe operation even during unwanted overcurrents or voltage fluctuations in the circuit.
